Scream and flail about.
You scream and flail, but Lisa holds your hand thightly. After few scary seconds of air roaring in your ears you find yourself standing firmly on stable ground, still screaming and flailing about. You don't quite remember the landing, if there even was any. One moment you were in middle free fall, on next moment you are standing upright on pleasantly stable ground.
Thick fog covers the ground up to your ankles. So thick, that it almost looks like liquid, making it impossible to see the actual ground. Everything is covered by a fog. You can see dark silhouettes of buildings on your both sides, about 7-9 meters away, but fog covers any details. While it is very silent here, you can hear weak whispers in the air...
"We are safe for a moment. Even if they jumped after us, they won't end in same spot with us and the fog of Old Town makes it very hard to
find anything here. So never let go of my hand." Lisa whispers. "But we still need to find good house to settle in. Many forgotten things wander down here, not all benevolent..."
Put the piece of the rifle I'm currently cleaning down and open the door slightly. "Hello? Who is it?"
Behind the door stands a kid of indeterminable gender. Probably between 12 and 15 years old. Dirt covers his/her face and hair and baggy patched clothes hide all of his/her body. The kid speaks with high shaky voice: "Could you please help me? I am being hunted by killers..."
Try to carry Lisa and keep running away from my house trying to stick to side paths and alleys.
You throw Lisa on your shoulder and keep running between buildings.
"Oh no, they killed me!" Lisa sniffs. "They... they tortured me..."
"Ooh, she's running again! This way, bro!"Go to the singularity's entrance (maintenance door) and send a greeting radio signal (knock).
"Don't worry, let's see if we can rescue you. Take this laser pistol. We might need it."
Hand out a laser pistol with its settings set to stun (a stun baton) to Lisa. Take the other one out of my other jacket pocket and get ready to use it.
You hand out the laser pistol and pull another one out from your pocket dimension. Your radio signal does activates automated opening sequence (not locked, opened by force of your knock). Inside the maintainance space is a standard manual space elevator (spiral staircase) going up and down, but no sight of the space janitor. Faint sound of steps echoes in the elevator.
"Down." Lisa whispers. "He definitely went down."
Hug Lisa.
"But, why do you need to go?"
Lisa smiles and returns the hug, dirty as it is. She smells like exteme lack of shower.
"Because I don't want to drag you into this. Those people are dangerous and won't hesitate to kill any upper city people crossing their way."
